Okay, Page 20, "Computer Science & Perl Programming", edited by Jon Orwant, Chapter 3, article title is Perfect Programming.
I'm not making this up:
Quote: When it's in effect, you can't use the bareword style of calling subroutines with no arguments (e.g. $result = mysub;) unless the subroutine was declared before its use, either with a prototype or with the subroutine definition itself.
EndQuote:
use strict 'subs';
print count; # an error with use strict 'subs'
sub count; # prototyping count() is sufficient
print count; # Not an error because Perl now knows about count()

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
